Key is the boards, as others have said. If it has updated boards and works, it's a neat item.
The metal is too thin, which can almost be seen in the pic J Daddy posted. Look closely at the door edges and you can sort of see slight "waves" in the edge of the metal along the vertical edges of the brick opening.
It's best to put it somewhere near the edge of the layout so you can easily take the lower side roof off for viewing the machines inside.
As mentioned, very important to have the addendum sheet for the instructions, or even if you start with a good board you can fry it.
Here's a link to the various documentation I found when searching on the Lionel site. I also noted that a motherboard part is actually shown as available, which is good news if true and that's all that is needed to fix a bad one. I'm not enough of an expert on the repair itself to say(mine was fixed before I bought it), but I found it interesting.
Good luck with your decision.
